In a statement, the Michigan athletic department said: "We are aware of an incident involving Fergus Connolly. We are still awaiting more detailed information before commenting further."

Lige would not release additional details of the incident.

"We have lab results that need to be submitted before charges can be brought," Lige said. "That will take several weeks."

Connolly, who joined Michigan's athletic department in 2016, has spent the last two seasons as the football team's "director of performance." He added director of Michigan's football operations to his job responsibilities prior to the 2017 season.

He made $255,000 in 2017, according to UM's annual salary report.

Connolly is the second football staff member under head coach Jim Harbaugh to have a run-in with police. In May 2015, Jim Minick, then Michigan's associate athletic director for football, was arrested on suspicion of drunken driving.

Minick pleaded guilty to operating a vehicle while intoxicated and was sentenced to eight months of probation, with a suspended sentence of 93 days in jail, with credit for one day served. Court records did not indicate that he ever served time in jail.

Minick offered to resign from Michigan, but then-athletic director Jim Hackett refused to accept it. Minick left the program in June 2017 to return to the military.

Before Michigan, Connolly spent two seasons, 2014-16, as director of elite performance for the NFL's San Francisco 49ers, including one season under Harbaugh.

He has consultant experience under his belt too, with stints working for the NFL's Jacksonville Jaguars and Cleveland Browns, the NBA's New York Knicks, the English Premier League and Australian professional rugby teams.

Harbaugh wrote the forward for "Game Changer: The Art of Sports Science," a book Connolly released in 2017 that pitches the idea evidence-based analysis and athlete-focused training are the path to success in sport, not necessarily big budgets or a heavy emphasis on advanced statistics.
